Abstract
A rod sensor (1) has in the vicinity of a sliding guide (17) of an outer tube (2) a bolt-like, smooth abutment (4) for an inner rod (3), which prior to the insertion of the inner rod (3) and prior to the constructional joining of the temperature sensor (1) to a switch base (10) is adjusted with a measuring screw (36) against the tension of a spring (39) to a predetermined adjusting amount (30) and is firmly connected to the outer tube (2) by a welding mechanism (40) or the like. Thus, a very accurate adjustment is obtained in the case of a simple construction.
Claims36
A temperature sensor comprising:
- at least one sensing rod, having a first rod unit (2) radially surrounding a second rod unit (3) and an abutment (4) radially surrounded by said first rod unit (2) for operationally supporting said second rod unit (3) against said first rod unit (2), said abutment having circumferential engagement faces for bearingly engaging said first rod unit (2) to prevent axial motion of said abutment relative to said first rod unit, wherein said engagement faces of said abutment have substantially smooth faces.
